Composite Geomembrane is a non-permeation material, which is compounded with geotechnical fabric and geotechnical film. It is mainly used for permeation proof drainage and reinforcement. Synthetic geotechnical film is divided in to one-cloth with one-film, two-cloth with one-film, multi-cloth with multi-film. Width: 1-6m, Weight: 200-1500g/m2, its physical performance specifications such as tearing resistance and breakage resistance are high. Since high molecule material and anti-aging agent are added in its production technology, it can be used in abnormal temperature environment.
Product Features
-
It integrates permeation inverse filter and drainage functions, and has various functions such as isolation and reinforcement.
-
It has high synthetic strength, large removal strength and high puncture resistance.
-
It has strong drainage capacity, large friction factor and small expansion factor.
-
It has good aging resistance, wide environmental temperature range and stable quality.
Application Range:
It is widely used in various projects such as water conservation, environmental protection, traffic and tunnel
Products: two-cloth with one-film (there are protective layers on the two sides of the anti soaking geomembrane) anti-soak
One-cloth with one-film (there is a protective layer on the anti soaking geomenbrane)
